SPECIFICATION forming part of Letters Patent No. 433,512, dated August 5, 1890.

Application filed July 30, 1839. Serial No. 319,142. (No model.)

, To all whom, it may concern.-

Be it known that I, RICHARD BURK, of Schwenningen, IViirtemberg, Germany, have invented an Improved Time-Oontrolling Apparatus, of which the following is a specification. v

This invention relates to an apparatus for recording the time the employs of a factory or other establishment are present.

The invention consists in the various features of improvement more fully pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of my improved time-controlling apparatus. Fig. 2 is a vertical section on line a m, Fig. 1; Fig. 3, a vertical section on line "y y, Fig. 2 5 Fig. 4., a horizontal section on line 2 2, Fig. 2; Fig. 5, a section similar to Fig. 2 of a smaller apparatus and showing the several hooks connected to an electric circuit, and Fig. 6 a face View of the apparatus shown in Fig. 5. Fig. 7 is a side view of one end of the drum h, showing the driving mechanism; Fig. 8, a top view thereof. Figs. 9 and 10 are modifications of Figs. 7 and 8.

The letter a represents a face plate provided with a suitable number of slots a, arranged in rows and with a numeral a beneath each slot. These numerals are shown in full lines in Fig. 1, and each of them is adopted by one of the employs. Below each numeral a there is hinged a plate I) by hinge 0. hen these plates are thrown up, they conceal the numerals a and display corresponding numerals b, which, however, are made in a different color. These numerals are shown by broken lines in Fig. 1. One set of numerals when displayed indicates the presence and the other the absence of the employs.

The face-plate a is fastened to a suitable casing u across which are hung a number of shafts (1. Upon these shafts turn the hooks d, projecting out of slots at and free to engage the plates b. The hooks cl are normally thrown into engagement with said plates by springs e; The rear end of each hook cl is by rod 9 connected to a lever or marker f, turning on shaft f, and the free end of which is from a power-shaft B by an intermediate train of gearing. The gear-wheel k on drum h meshes into pinion 71. as before. This pinion meshes into wheel h that receives motion from wheel 72 fast on shaft 71. This shaft carries wheel 71 that intergears with the wheel h fast on work-shaft B.

The record'sheet h is divided by a series of lines into rectangular spaces. Between each pair of vertical lines one of the lovers f marks the record sheet, while the horizontal lines divide the recordsheet into spaces cor responding to days, hours, fractions of hours, or other time.

The operation of the apparatus willbe read ily understood. When an employ enters, he draws his plate 11 down. This causes the rear end of hook d to rise, and this in turn will cause contact between the marker f and the record-sheet it. As the latter revolves, a line will be drawn upon it corresponding in length to the length of time the employ is present. hen the employ leaves, he throws his plate b up to cause a disengagement between the marker and the record sheet.

In Figs. 5. and 6 the face-plate a is provided with a metallic plate 2', and the hook cl is pro vided with a corresponding metallic plate "6'. The metallic plates it constitute electric contacts and are connected to the wires j of an electric circuit. The wire j may lead to an ordinary indicator 70, such as used in hotels. This indicator is placed in the directors room. WVhen the hooks d are swung down, the cir= cuit will be closed and the indicator will drop its number to automatically indicate the presence of the employs.

The advantages connected with this apparatus are its great simplicity and its certainty of operation. Moreover, it cannot be tampered with, and it indicates at a glance whether an employ is present or absent.

WVhat I claim is 1. The combination of face-plate a, with a series of plates 1) hinged thereto, and with hooks d engaging said plates, and with markers f connected to said hooks, and with a movable record-sheet acted upon by the markers, substantially as specified.

2. The combination of slotted face-plate a, with a series of plates 6 hinged thereto, spring-hooks cl, projecting through said faceplate, markers f, connected to the springhooks, and with a movable reeord-sheet acted upon by the markers, substantially as specified.

RICHARD BURK.
